“…Simulation tools can be divided into two types: i) commercial tools such as Power System Simulator for Engineering (PSS/E), CYME Power Engineering, Power World Simulator, Power System Simulator (Simpow), LabVIEW, etc., and ii) customized toolboxes developed for academic and research purposes. Matlab, which is a programming platform widely used to obtain the solution for load flow studies and the VSA of large systems, is described in (Rao and Yuan, 2022;Salama and Vokony, 2022). This analysis was carried out with the help of several toolboxes and packages, such the Electromagnetic Transients Program (Mahseredjian and Alvarado, 1997), Educational Simulation Tool (Vournas et al, 2004), Power System Toolbox (Chow et al, 1992), Sim Power Systems (Sybille, 2004), Power System Simulation Package (Zimmerman, 2005), and Power Analysis Toolbox (Schoder, 2003).…”

Voltage stability is a critical aspect of power system operation, ensuring the reliable and efficient delivery of electrical energy to consumers. Recently, voltage stability in the power system has received much attention. The primary cause of voltage instability is the lack of real and reactive power generation to cope with the continuous demand increment. Maintaining voltage stability while planning, controlling, and assessing the system’s security is a difficult task for power system engineers. From knowledge of past incidents, a lack of reactive power is identified as the primary cause of voltage instability, which may further lead to the total collapse of the system. The importance of voltage stability assessment is essential to maintain the integrity of power systems. It helps prevent voltage instability, which can lead to cascading failures and widespread outages. This paper uses various parameters, including load demand, generator capacity, and system impedance, to develop voltage stability indices (VSIs). The paper mainly focuses on the idea of VSIs that have been developed in order to monitor and control the criticality of the power system. The voltage stability indices for transmission and distributed systems, as well as their subclasses, are thoroughly reviewed in this study. Furthermore, traditional voltage stability methods, as well as various software tools for monitoring the voltage stability problems, are also discussed. In addition, the development of VSIs and its related concepts are clearly described in this paper. This comprehensive survey provides a decent groundwork for future work in this area, and assists professionals in selecting the optimal VSI for various applications. Moreover, it provides a concise overview of methods and the importance of voltage stability assessment in both transmission and distribution systems.

Short-circuit current calculation is one of the most basic and commonly used calculations in power systems, which is related to the setting of distribution network relay protection, selection of electrical equipment, identification of short-circuit accidents, and so on. This paper establishes the grid structure of grid short-circuit with 220kV substation as the boundary, analyzes the current composition of grid short-circuit, designs the basic method of grid short-circuit current calculation based on the Davignan equivalence model, and calculates its steady-state value. In the calculation of grid short-circuit current parameters, the idea of casting and cutting capacitors is introduced to construct the measurement strategy for short-circuit current capacity parameters. Based on the semi-physical simulation test technology, the semi-physical simulation verification platform of grid short-circuit is established by combining the real-time digital simulation system, and the error between the calculated value of short-circuit current and the simulation measurement value is analyzed by this platform. When the short-circuit capacity parameter is 100MVA, the measurement error is only 1.46% near the extreme load, and the minimum error of short-circuit current and in-ring current obtained by the semi-physical simulation platform can be controlled to 2.45% and 4.11%, respectively, and the range of transient peak coefficient error is in the range of [-1.66%,1.39%]. The application of the semi-physical simulation platform for measuring grid short-circuit parameters has high accuracy and guides optimizing grid configuration.
